U.S. stock markets experienced a significant rally, with the Dow Jones Industrial Average gaining 462 points, marking a resurgence for the index after a week of declines. The S&P 500 and Nasdaq also saw gains, rising 1.7% and 1.8% respectively. However, the tech sector faced pressure due to declines in stocks like Google and NVIDIA, which ended the day slightly down despite earlier optimism. Asian markets are expected to open higher, buoyed by Wall Street's performance, with Japan's Nikkei 225 futures indicating a stronger start at 38,190. The recent surge in Bitcoin, nearing $100,000, has also contributed to positive sentiment across global markets. Amazon's increased investment in artificial intelligence has positively influenced its stock, contrasting with the struggles of other tech giants.
